Time for peppering user passwords in Django?

[linluc]

Peppering passwords has been a controversial topic widely discussed in many stack overflow questions. Having ran my 20+ personal email addresses through HIBP page the findings are clear: all emails/passwords of mine that had been leaked fall in the following categories: SQL injections, mis-configured databases, exposed database admin panels or strayed database backup files.

And that’s exactly what a pepper value in the hashing process is protecting from. Breaching the whole server with physical access to the file system is rather rare nowadays.

According to this NIST document [ Digital Identity Guidelines Authentication and Lifecycle Management]

​https://pages.nist.gov/800-63-3/sp800-63b.html :

“In addition, verifiers SHOULD perform an additional iteration of a key derivation function using a salt value that is secret and known only to the verifier.”

So, why not in Django?
